V10 has code to enter USB SPI flash write mode directly when XCS0 button in the minidemo board is pressed during boot.

Instructions on how to write the patch to SPI FLASH.

Note: For SD card there should be ne problems, copy any files in whatever order you like to the SD card.

For writing the patch to a new SPI flash, use this sequence to avoid memory corruption:

1) Connect MiniDemo board to PC. Connect both the UART cable and the USB cable.
2) give 'reboot 4' command from the UART command line. Flash will show up on the PC.
3) With Windows PC, format the flash to FAT and copy Patch10C.dlx to the flash.
4) rename Patch10C.dlx to boot.dlx in the SPI flash.
5) create a new folder SYS in the SPI flash root.

6) reboot the board with the button pressed (press button and short the reset jumper momentarily)
7) board will come up in the PC as SPI flash, UART screen will show "Patch v10" (see below)

8) SPI flash can now be used safely. UART cable is not needed any more.

For software development, use the SD card as the System Disk instead of the SPI flash. This is because the SD card can be reformatted easily with a SD card reader in case of software error that dead-locks the board. When your software development is complete, copy the finished software to the SPI flash.
